BARTON H. J ENKS, OF BRIDESBURG, PENNSYLVANIA.

Specification forming part of Letters Patent No. 141,441, dated August 5, 1873; application filed May 2,1873.

CASE 0.

To all whom it may concern:

Be it known that I, BARTON H. hours, of Bridesburg, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Bolsters for Spindles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making part of this specification, in which- Figure 1 is a side view of the bolster applied to a section of rail. Fig. 2 is a vertical transverse section through the same. Fig. 3 is a side view of the bolster without its sleeve. Fig. at is a side view of the sleeve.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improvement on spindle-bolsters for spinning-frames 5 and consists in a metallic sleeve or spindle-bearing applied so as to receive lateral play from the spindle, and thus allow the latter to find its center of gravity when rapidly rotated, as will be hereinafter explained.

The following description of my invention will enable others skilled in the art to understand it. 1

In the accompanying drawings, A represents a bolster-shell, consisting of an enlarged head, which is cupped at c for oil, and a reduced neck, a, which is received into the rail 0 and held therein in any suitable manner. Inside of this bolster-shell is a sleeve-bearing, B, for the spindle S, which sleeve is prevented from turning about its axis by means of a lug, g, or other analogous device, on the neck of the bolster-shell, which enters a vertical groove, g, made into the outer surface of the sleeve. The sleeve B, which is notched at b for allowing oil to flow to the spindle, is supported by the pin g, and it is somewhat smaller in its diameter than the interior diameter of the bolster-shell, which allows the sleeve to receive lateral play from the spindle for the purpose of allowing the spindle to find and maintain its center of gravity when rapidly rotated.

If desired, an India-rubber or other suitable spring may be applied in the space between the sleeve and bolster, which spring should not offer a greater resistance to the spindle than it can overcome in finding its center of gravity; otherwise the spindle would vibrate when rapidly rotated.

I do not claim, under this application, a spring applied outside of a spindle-bearing, as this is Patent marked case A and B, and bearing even date with the filing of this.

What I do claim as new, and desire toisecure by Letters Patent, is-

The sleeve B for encircling the spindle, constructed and applied within the cylindric bolster-shell, so that it shall form a close-fitting upper guide and bearing for the spindle and yet have sufficient lateral movement in any direction within the bolster-shell to permit the spindle to find its center of gravity and at the same time shall be positively restrained from revolving with said spindle, all as herein described and set forth.
